The drive bearing 57 includes an operating rod 58 which is eccentrically disposed below a predetermined step from the rotating shaft and protrudes toward the driven bearing 53 . The operating rod 58 and the rotating shaft of the driven bearing 53 are engaged with each other. With such a configuration, a rotational driving force of the lifting motor 59 is transferred via the drive bearing 57 and the driven bearing 53 to act to cause the jig 45 to move up and down. At this time, the clamping member 45 is arranged in a vertical direction in the lower portion of the table 5 and positioned in a sleeve 61 which is fixed by a bracket block 63 , so that the clamping member 45 can be guided up and down.

The rotary drive part 71 includes a rotary motor 79 which is arranged on one side of the bush 61 , a drive wheel 77 which is connected to the drive shaft of the rotary motor 79 , a driven wheel 73 which is connected to a peripheral surface of the book 61 , and a belt 75 , which operatively connects the driving wheel 77 and the driven wheel 73 to transmit the driving force therebetween. When the bushing 61 is rotated by the rotary drive part 71 , the clamping member 45 is also rotated. The bearings 62 are installed on the circumferential surface of the socket 61 or the clamping element 45 in order to ensure easier rotation. The rotating motor 79 is designed such that it rotates synchronously in accordance with the rotation of the drilling motor 33 .

The saw processing arrangement 41 further comprises a clamping release part 65 , which is arranged on an upper section of the clamping part 43 , and which is designed such that it releases the saw blade 21 clamped in the clamping part 43 . The clamping release part 65 contains a release pin 67 for pressing the hook 49 in a release direction and a release cylinder 68 for moving the release pin 67 forward and backward with respect to the hook 49 . The release pin 67 is installed in one piece with the socket 61 in an up and down movable manner, and the release cylinder 68 moves the socket 61 with respect to the clamping element 45 up and down. When the release pin 67 runs downward through the release cylinder 68 , the clamping between the saw blade 21 and the hook 49 is released .

The sawing machine, which is constructed as described above, comprises, as shown schematically in Fig. 3, the table 5 for storing a plate member, the saw blade cylinder 17 for moving the saw blade 21 up and down, the rotary drive part 31 of the receiving part for the Saw blade for integral rotation of the saw blade 21 and the receiving tube 13 for the saw blade, in which the saw blade 21 is received, and the lifting drive part 51 of the clamping part for moving the clamping part 43 , which is clamped to the saw blade 21 , up and down .

The various parts and functions of the sawing machine are controlled by a controller 81 . The controller 81 stores predetermined data relating to saw processing and executes drilling and sawing functions in the plate element 9 based on an external data record which is entered into the controller 81 via an operating part 83 and based on stored data. The controller 81 just controls the release cylinder 68 for releasing the saw blade 21 , which is clamped in the clamping part 43 .

A saw processing method using an embodiment of the saw machine according to the present invention will now be described in detail with reference to the flow chart of FIG. 7. To perform a sawing function, the predetermined plate member 9 is first placed on the table 5 (step S1). The controller 81 controls the table 5 vertically below the saw blade 21 according to the externally input and stored data for positioning the plate member 9 which is used (step S2). When the plate member 9 is suitably positioned, the drill motor 33 is driven to rotate the saw tube 13 for the saw blade (step S3), and at the same time the saw cylinder 17 is lowered (step S4) to perform a drilling function on the plate surface of the plate member . When the drilling work is completed (step S5), the rotational speed of the saw blade 21 which is passed through the plate member 9 is gradually reduced due to a stop signal supplied to the drilling motor 33 (step S6), and at the same time, the saw blade 21 becomes lowest point is lowered by pressing the saw blade cylinder 17 so as to be clamped in the clamping part 43 (step S7). Since the rotary motor 79 rotates synchronously in accordance with the rotation of the drilling motor 33 , a clamping position of the saw blade 21 is always compliant with the clamping part 43 , so that the saw blade 21 is thereby clamped precisely. This prevents damage and breakage of the saw blade 21 .

Fig. 6 shows an exploded view of the drilling part 23 of the saw blade 21 , which is clamped in the hook 49 of the clamping part 43 . When the saw blade 21 is clamped in the chuck part 43 , the controller 81 controls the lifting motor 59 of the chuck part to rotate the drive bearing 57 (step S8). At this time, the rotation of the operating beam 58 of the drive bearing 57 , which is eccentrically placed, causes the driven bearing 53 to move up and down so that the chuck member 45 is moved up and down. Thus, as shown in FIGS. 4 and 5, the saw blade 21 is moved up and down. When the chuck part 43 starts to move up and down, the controller 81 simultaneously controls the movement of the table 5 (step S9) to cause a desired sawing operation to be performed on the plate member 9 .

When the sawing operation is completed (step S10), the controller 81 stops the lifting motor 59 (step S11) and releases the clamping of the saw blade 21 by lowering the release pin 67 via the release cylinder 68 (step S12). Next, the saw blade 21 is moved to an initial position by moving the saw blade cylinder 17 up and down (step S13).

Referring now to FIG. 9, a combination of a saw blade and a drill bit member 90 for use in the saw machine 1 of the present invention is illustrated. The combination element 90 contains a drill bit section 92 and a saw blade section 94 . The drill bit section 92 forms a tip at one end of the combina tion assembly 90 , which allows a user to drill a hole in an object such as an object. B. drill a plate material to provide access to the object for the saw blade section. When the hole in the object is formed over the bit section 92 , the combination member 90 can be passed through the hole to facilitate cutting out a desired shape in the object over the saw blade portion 94 . A plurality of teeth 96 are formed on an edge of saw blade portion 94 to facilitate the cutting of the Whether jekts. It is possible that a straight cutting edge is formed on the combination element 90 , which replaces the plurality of teeth 96 . The combination arrangement can be configured in any dimension that is suitable for meeting the special needs of the work to be performed. For example, the diameter of the drill bit section 92 can be larger or smaller, or the number of teeth 96 on the saw blade section 94 can vary. Also, the combination assembly 90 is preferably made of a suitable material, such as. B. hardened metal, which is typically used for cutting wood, plastic, metal or other material.
